Abstract: The designs of dual-band and wide-band microstrip patch antennas with conical radiation patterns are presented in this paper. The antenna
is composed of a square-ring patch that is shorted to the ground plane through four shorting walls. Three resonant modes with conical radiation
patterns can be simultaneously excited in the antenna structure by a patch-loaded coaxial probe inside the square-ring patch, and they can
be designed as a dual-band operation. Moreover, by adjusting the width of the shorting walls, the three modes can be coupled together to realize
a wide-band operation. From the obtained results, the 10 dB impedance bandwidths at lower and higher operating frequencies are respectively 42
and 8% for the dual-band antenna design, and the wide-band design exhibits an impedance bandwidth of about 70%.
